China's electric vehicle industry has gone through more than a decade of development. In practice, it has explored a new path of relying on technological innovation to develop and grow, and is entering a period of rapid development and important opportunities. In 2014, General Secretary Xi Jinping emphasized during the inspection of Shanghai Automotive Group that the development of new energy vehicles is the only way for China to move from a big automobile country to a car power. This important discussion has drawn a blueprint for the development of China's auto industry. Facing the future, we must adhere to the emerging technologies such as new energy and intelligence to lead the development direction of China's automobile industry, and support the automotive industry to achieve high-quality development with technological innovation.


Collaborative innovation in production, education and research, China's new energy vehicle development has made great progress. The scale of the new energy vehicle market has maintained a rapid growth momentum. In 2017, the sales volume of new energy vehicles in China reached 777,000, an increase of 53% over 2016. The new energy vehicle industry structure is more optimized, with passenger car sales exceeding 74%, reaching 579,000 units. The vehicle power battery capacity reached 200GWh, and the number of public charging piles put into operation nationwide exceeded 210,000.


Key technologies for new energy vehicles have made important breakthroughs. China's power battery performance indicators have steadily improved, and important breakthroughs have been made in basic materials and common technologies such as rare earth permanent magnet materials and position sensors. The key performance indicators of motors have reached international standards, and fuel cell power system components and integration technologies have made significant progress. A number of independent brands of networked vehicles have entered the market, and autonomous driving technology is entering an important stage of road testing.


The new energy vehicle market has taken a pivotal position in the global industrial system. China's new energy vehicles have an annual production, sales volume and cumulative sales volume of 50% of the global market. It is the world's largest new energy vehicle market, and has become a model for international energy conservation and emission reduction and climate change through the upgrading of the automotive industry. China's new energy vehicles have entered dozens of countries, and key components such as power batteries and drive motors have entered the supporting system of multinational vehicles. The world's major new energy vehicle products have entered the Chinese market.


Seize the new scientific and technological revolution and major opportunities for industrial transformation, and enhance the motorized and intelligent technological innovation capability of China's automobile industry. In recent years, electrification and intelligence are leading the new direction of the development of the global automotive industry. In 2016, Norway, Sweden and other countries announced that they would stop selling fuel vehicles in 2030. The United States, Japan, India and other countries have announced roadmaps for electrification and intelligence. Multinational auto companies have also launched motorized and intelligent operations. plan. At the 8th Clean Energy Ministerial Meeting held in Beijing in 2017, the [email protected] Target Initiative”, in which 30% of cars should be new energy vehicles by 2030, was proposed. The development of China's automobile industry must conform to the global trend of scientific and technological innovation and development, firmly grasp the new round of scientific and technological revolution and major opportunities for industrial transformation, adhere to the development path of electrified and intelligent vehicles with Chinese characteristics, and give full play to China's high technology and big market. The advantage of organic combination, in the more open market competition environment, work hard and catch up.


The first is to continue to overcome the key technical problems of electric vehicles. Driving range is the bottleneck restricting the development of pure electric vehicles. Simply increasing the number of vehicle batteries will lead to an increase in vehicle kerb quality and a rise in unit mileage power consumption. It is necessary to strengthen basic research on battery materials and manufacturing processes to improve energy and power density of power batteries. As well as the weight reduction of the entire vehicle, the driving range will continue to increase. It is necessary to fully exploit the excellent electrothermal conduction characteristics of graphene to improve the energy storage performance of the battery. Aiming at the space layout and thermal management requirements of the unique battery system of electric vehicles, special optimization design is designed to solve the problem of small discharge rate and low capacity in winter. Through the lightweight technology innovations in vehicle body materials, structural design, parts processing, and vehicle manufacturing processes, the energy utilization efficiency of new energy vehicles is improved and energy consumption is reduced. To strengthen the research on the recovery and cascade utilization of power batteries, the life of the power battery for automobiles is two-cycle. After decommissioning from the vehicle, it can also be used for a long time on the energy storage station.


The second is based on the actual development of fuel cell vehicle technology in China. China has a variety of hydrogen sources and sufficient supply. The development of fuel cell vehicles has a unique market environment. Fuel cell zero emissions, high energy efficiency, long life, dynamic battery dynamics, fast energy recovery, "electric-electric hybrid" can complement each other. This is the technical feature that China has formed in research and development and demonstration applications for more than a decade. It is necessary to make full use of the existing charging pile system in China, and use the fuel cell electric-electric hybrid system to extend the driving range and make up the mileage short board, which can solve the problem of complementary charging and hydrogenation. Adhere to the pioneering development of fuel cell vehicle transit logistics industry, on the one hand to expand the long-distance bus and taxi market; on the other hand, to adapt to the needs of online shopping flow, the development of extended-program small logistics vehicles. The next step is to deepen international cooperation and collaborative innovation in the field of fuel cells, and further enhance China's influence and rulemaking capabilities in the international emerging technology industry.


The third is the advanced technology and R&D and industrial application of intelligent driving vehicles. With the development of big data and artificial intelligence technology, intelligent network and self-driving cars are welcoming new opportunities. Safety, green, convenience and sharing are the four core elements of automatic intelligent driving technology. Self-driving cars can be divided into four stages: assisted automatic driving, partial automatic driving, authorized automatic driving, and high/complete automatic driving. Each stage has its own research and development focus. Auxiliary automatic driving mainly studies the car's perception of the surrounding environment, such as ABS (Brake Anti-lock Braking System), ESP (Car Body Electronic Stability System), tracking cruise and automatic parking, etc., can make timely response according to real-time road conditions. At present, assisted automatic driving has entered the stage of technology promotion and application. Part of autonomous driving must first implement network networking, study the connection of vehicles and networks, and make scientific decisions to improve the early warning and response capabilities of the driving process. The focus of authorized autopilot research is on the linkage of cars, nets and roads. The basis of high/complete automatic driving is to study the integrated intelligent transportation system of people, vehicles, networks and roads. At the same time, it is necessary to establish corresponding policies and regulations and monitoring systems to ensure safety. Traditional cars usually have 2-3 sets of control and information networks. The connection between systems is not connected. It is difficult to realize real-time operation of driving and driving. Electric vehicles are the first to realize the communication and management system of the internal and external control systems of the vehicle network. The maturity is increasing and it is the best carrier for autonomous driving.


The biggest challenge facing intelligent networked vehicles is based on the dynamic decision-making and operating system of various information comprehensive decision-making. The realization of the function of automatic driving requires the intersection of multi-disciplinary knowledge and the integration of multi-domain technologies. The world's major countries and multinational car companies have systematically deployed in the field of automatic driving, and the future market competition will be fierce. China must firmly grasp the rare development opportunity of "electric vehicle + intelligence", scientific planning, advanced layout, adhere to the enterprise as the main body, promote the collaborative innovation of all aspects of production, education and research, and make the market application of new technology an important force. Point, gradually realize the commercial operation of autonomous driving.


Building a good industrial innovation ecology and promoting the transformation and upgrading of China's automobile industry under more open conditions General Secretary Xi Jinping demonstrated to the world the confidence and determination of China to further deepen reform and expand opening up at the opening ceremony of the 2018 annual meeting of the Boao Forum for Asia. China's auto industry will face a more open market competition environment. The relevant state ministries and commissions also announced specific measures for the further expansion of the automobile industry. In a more open environment, we must further enhance China's core competitiveness in the field of new energy vehicles and smart driving, and drive the transformation and upgrading of the automobile industry.


Maintain continuity and effectiveness of policy tools. New energy vehicles and intelligent development require policy tools that comply with internationally accepted rules to support the supply of common technologies and foster market consumer groups. It is necessary to deepen the reform of electricity prices, especially to promote the role of volatile electricity prices in the development of electric vehicles. It is necessary to plan ahead, deploy ahead, and actively and steadily introduce the development plan, technical standards, support policies and management regulations for automatic driving to ensure safe and effective operation, and gradually enter the stage of marketization and scale application.


The transformation and upgrading of the automobile industry is a long-term process. Although China's new energy vehicles started early, the overall strength is not strong and the advantages are not obvious. In the new era, we must continue to strengthen the technology research and development, industrial upgrading, policy support, and business innovation of new energy vehicles, and strive to improve the supply quality of new energy vehicle products and create greater economic and social benefits. We must grasp the new opportunities for the intelligent development of automobiles, systematic research, careful planning, and advanced deployment. Encourage the enterprise-based collaborative innovation of production, education and research, boldly explore, and steadily advance, and strive to occupy the competition commanding height of autonomous driving technology. We must mobilize the strengths of all parties, gather together, work hard, give full play to our own advantages, strengthen international cooperation, fill in shortcomings in technology, build a better industrial innovation ecology, and promote China's automobile industry to move towards the mid-to-high end. Quality development makes new contributions.
